I’ve done it before, and we are doing it again. Our dining table is in poor condition, so we sanded the top off and we are going to restain it. You can see the white marks from plates and pots that were too hot, and even some sharpie marker marks from the kids. We sanded it and started to stain it. I put it on a bit too thick so we might sand that a bit before coating it with a water based sealer.
